' Specification of Letters Patent.

Application filed March 29, 1909. Serial NOQ J SSASG.

zen of the United States, residing at Ber Wyn, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Stapling Mechanism, of which the following is a specification.

In my pending application, No. 483,237, filed March 12, 1909,"there is disclosed a stapling mechanism for binding pamphlets from arotary printing machine, the arrangement therein disclosed being particularly applicable for stapling a plurality of pamphlets formed by superposed webs which are slit along longitudinal lines, but not longitudinally folded, the axes of the staple forming and setting rolls being parallel to the axes of the form and impression cylinders of the rotary printing machine. The present invention covers the use of a similar stapling mechanism with axes at right angles to the cylinders of'the press, a

' plurality of pamphlets being produced by longitudinally folding a set of webs and slitting the same, whereby the size of the product is increased with respect to thenumber of pages, as compared .to the mechanism disclosed in said pending application. The present case utilizes the idea ofa plurality of stapling devices with double devices for making two staples and inserting the same at a single operation, and completing a plurality of pamphlets at each operation. All the disadvantages due to the use of paste or glue are avoided, and the stapling devices 7 always move in the same direction as the run of the webs, whereby a high degree of speed can be obtained. The products are all bound together before being transversely cut and e folded, and no tapes or guides are needed to insure the travel of the webs to the delivery. The web printing mechanism is adapted to print a plurality of webs, which aresthen longitudinally slit 'and folded, then out transversely on the leading margin, then stapled on a transverse line, then folded on the same line after they are severed, and thence delivered to a rotary fly and a delivery apron.

In the accompanying drawingsFigure 1 is a diagrammatic end elevation, partly in section, showing longitudinal folders and the stapling rolls. Fig. 2 is a diagrammatic elevation of thestapling former anddrum. 3 is a diagrammatic elevation of the folding blades showing openings for passing the ribs. Fig. 5 is a plan of the product.

In Fig. 1, A and B are longitudinal folders at the end of a printing mechanism not shown. The webs C and D pass over the .roller I and under the wheels 2, 3, 4 and 5,

and are slit longitudinally by the slitter 6, at the middle, and thence pass from the longitudinal folders between the rollers 7, 8',- 9 and 10, having been slit again at theapex of the formers A and B by the known slitters 11 and 12. Thence the webs pass between the rollers 13 and 1 1 where they are associated, and are slit again by the slitter 15 which is at the middle of the roller 14. Thence the associated webs pass between the carriers C and Dwhere. they are stapled as hereinafter described, and then folded transversely and taken off betweenv the rollthe barrier roll with the ribs for clenching l the staples. Fig. 4 is an elevation of one of ers 16 and 17 and delivered by the rotary fly 18 to the apron 19. 4

With respect ,to the wire'stapling devices E indicates a pair of rotary cylinders. mounted upon the same shaft which is provided with rotary heads 6 at each end and'at the middle for holding the wire spools 20 and 21. For forming the staples each cylinder E has a pair of double armed staple formers 22 and 23 each of which simultaneously forms two staples. The wire having been fed from the spools 20 and 21 passes be tween the rollers 24 and 25 and is cut by the cutters 26 to the desired length and thence passes through guide-ways 27 where the formers 22 and 23 press the wire into pockets 28, 29, 30 and 31 which are arranged in-pairs on the cylinder C','in position corresponding to the arms of the double formers 22 and 23. The staples so inserted in these pockets are by known mechanism driven through the webs as they pass be- I tween the c linders C and D, two staples beingsimu taneously inserted in each sec *tion of the product, or four in all at'each operation, there being two sets of webs passing between the cylinders C and D in consequence of the longitudinal slit made by the knife 15.

fold the rollers 16 and 17. This cylinder also carriesthe means for pinning and cutting the webs by the knives a, Z2, and d, and the pins, e,

and h, operating against the carrier C which holds the matrixes 2', j, k and Z. The carrier D also has two pairs of ribs 32, 33, 34 and 35 for clenching the staples when they are driven against them. As shown in Fig. 4:, the folding blades have openings 40 cylinder,

yerse folders .or pamphlets, located side by side,

to enable them to pass the ribs.

v Aside from the features above indicated the mechanical devices and details for forming and setting the staples may be those in common use or otherwise as desired; 1

The drawings show two webs which are transversely folded and associated. By increasing the number of webs the product will be correspondingly increased, and it is obvious that at each operation of the trans- F, G,'H and 1', two signatures are folded off between the rolls 16 and 17. The book or pamphlet is printed with the column rules parallel with the axes of the printing which enables the products to be sta led at the middle and on the transverse fol ing line, two staples being simultaneously inserted on this line so that the book or amphlet is completed atone operation.

This is a decided improvement "over those machines which only staple'onestaple at a time and require two sets of mechanisms for completing a book or. pamphlet.

.1 claim:

1. The combination with longitudinal web folding and slittingdevices', folding and".

transverse cutting carriers to which the slitted webs aredelivered in a plurality of sections side by side, said carriers being provided with rows of plural staple holding and setting devices, arranged for simultaneous operation on a line transversely of the webs, and rotary wire-spool-carrying and staple-forming means tosupply staples to said devices.

2. The combination of adplurality of longitudinal web folders an slitters, transverse folding and cutting carriers, means to associate webs from said folders and deliver the same to the carriers, a lon itudinal slitter operating on the webs a ter they are associated and before they reachthe carriers, whereby they are delivered thereto in parallel longitudinal sections, and means to simultaneously insert staples in said sections on a transverse folding line.

3. The combination of a pair of transverse web folding and cuttin carriers, a plurality of staple holding an setting devices arran ed 1n a row on said carriers, means to de i vei' associated webs to said carriers in longitudinal sections running side by side between the carriers, and means to supply staples to said devices, including rotary coaxial cylinders and heads and wire spools carried by said heads.

-In testimony whereof, I affix my signature in presence of two witnesses.
